I bought a very similar version of this for $50 on Craigslist. It's the Rockwell / Delta 37-600. The setup looks to be the same, just different badges. Mine has a 1/2 hp motor, which I'm not sure is original, as I've seen others with 1/3 hp motors.
Long story short, the 1/2 hp motor is strong enough to go through hardwoods without slowing down and makes a really clean, flat cut. Overall, the jointer seems to work pretty well, but it's all in the setup. Since the outfeed table isn't adjustable, you've got to be dead on with the knife setup to make sure they are even with the outfeed table. This is simple enough to do with a good straight edge, but it does take some patience. I'm not sure how well this would work with rabbeting or angled jointing, as the fence set up isn't the most user friendly. Fortunately all I'm using mine for is getting a nice flat bottom and perfect 90 degree edges.
I've attached a couple of pictures of mine, before and after I restored it. Turned out pretty nice for $50 plus another $50 or so in paint, penetrating oil, and sanding wheels.
